Abstract
A fixed angle centrifuge rotor is provided including a rotor body having an upper surface and a plurality of tubular cavities extending from the upper surface to respective bottom walls. A pressure plate is operatively coupled to the bottom walls of the tubular cavities and is configured to transfer torque to the bottom walls. The pressure plate is configured to be directly coupled to a rotor hub and to receive torque directly from the rotor hub.
